[Flightgear-devel] MP Chat text length in FG
Dear List, I noticed a mismatch and want to suggest a fix, or ask for an explanation: In source code I found a max. text length of 256 (bytes) chars in MP server and FG itself. I made some tests and saw that this text length does not work. The text is not being transferred if it gets too long. UDP can transmit 65KB so its out of the game, I think. I have tested with OpenRadar and a FG instance. The max. count of transfered chars is in OR: 128 chars in FG from chat dialog less between 110 and 120. As OR does not care about the chat message length, there seem to be restriction in reception (128 bytes) and sending(~110-120) in FG I know 128 is already a lot if you fly beside typing and reading. But for ATIS messages etc. it is nice, if you don't have to care for some less bytes, which might cause the message is not received. Guess the issue is somewhere in FGs chat message handling...

[Flightgear-devel] Slave flightgear as external view to monitor traffic
Dear List, We have the idea to use flightgear to display the external view onto the airport for OpenRadar. (OpenRadar Version 2) This is something that would add a necessary grade of realism and would make ATCing more attractive. As it is possible to use flightgear as view slave for another fg instance, this seems to be possible. I think I need an invisible airplane, position it a the tower position and tell it, where to look to. Is there a documentation that helps me? I guess there is a protocol that I have to use, once I have started the flightgear instance. Thank you!

Correct. When I originally implemented the MP chat function, I intended to enhance it so that chat would be filtered by the tuned frequencies. However, before I managed to do that, FGCom was developed and it quickly became obvious that it was a much better solution, as well as being more realistic. True, FGCOM is much better. But many ATCs use the MP chat to help the user to understand and 'read back' the values. Additional many users don't use it, at least for now. The ATCs I know, accept MP Chat. Several ATC 'aircraft' and OpenRadar have features to support MPChat ATCing. It is trivial to add, and I'll take a look after the release is complete. I'll also check with Matthias to see if there's any HLA issue I should be considering.

[Flightgear-devel] Add/Set properties to/in MP Protocol
Hi List, I am working on OpenRadar and miss some features that would really be nice to have: Active tuned in frequency: There is a property for that in MP protocol, but as much as I have seen, it contains always the same frequency and does not change with the radio. Potential Usage: In a region with many ATCs, like in the triangle around EDDF, there is much noise to ignore in MP chat, because all speak over one channel. If we would have the set aircraft frequency transmitted, the ATC could filter those messages that match his frequencies. We would have a much better realism and ATCs had a better overview. On my side I have implemented this feature already, but it is hidden, as it waits for the FG Change. Squawk codes The big difference between FG und the reality in terms of ATC is that if there should be a Squawk transponder build into the model its data do not reach other clients. Potential Usage: Most of you will know how it is used. I can imagine that these codes influence the coloring (e.g. emergencies) and give extra information to the ATC (flight state). I do not know exactly, but I think adding these values is a rewarding small extra job. Volunteers!!!

Re: [Flightgear-devel] Questions to MP Protocol
Hi Stuart, Thanks for your reply. This was the issue: Am Montag, den 24.12.2012, 22:45 + schrieb Stuart Buchanan: - There's a bug in our XDR implementation that we pad each character to a 4-byte word. See src/Multiplayer/multiplayermgr.cxx line 316, 728, 739. (I think I introduced the bug when I wrote the original string XDR parsing). I'd recommend comparing your XDR encoding to check that it matches. (Chat messages are not in use for multiplayer messages I think...) This was a difficult thing: When I added the 4 bytes padding, Other OpenRadar instances got the chat message back, but all the other FG users got nothing. So I omitted the pad again and changed the reception, to recognize partner side padding. Now, all my tests in this matter have been successful... Thank you and a Merry Christmas!

[Flightgear-devel] Questions to MP Protocol
Dear List, I am looking for someone with whom I can discuss some detail questions about FGs MP protocol. I have written an application that communicates with running FG instances. I can receive all messages, but sometimes my messages seem to be lost. My understanding is this: Chat messages are sent inside the position update packages. At first I have sent them only once, but now I send them at least 10 times for at least 3 seconds. This code is there to prevent UDP drops. But it did not help. Is there a hidden bug in my sending logic or do I something completely wrong?
